Andrew was the brother of Simon Peter. Both he and his brother Peter were fishermen by trade and were called from their fishing by Jesus to follow Him, promising that He would make them “fishers of men.”

The Gospel of John teaches that Andrew was a disciple of John the Baptist, whose testimony first led Andrew and John the Evangelist to follow Jesus (John 1:35-40). Andrew at once recognized Jesus as the Messiah, and hastened to introduce him to his brother (John 1:41).
